Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to portal sealing means, and more
particularly to a device and its method of use for sealing the small
opening between two surfaces such as a door and its frame. The device
provides sealing as well as a structural support means with great strength
and may be quickly disengaged for moving one or both of the engaged
elements.
2. Description of Related Art
The following art defines the present state of this field:
Landgraf et al., U.S. Pat. No. 5,089,215 describes a method of securing a
cylindrical centering pin for a nuclear fuel assembly in a bore formed in
a plate includes introducing an end of the centering pin into the bore
until at least part of a coaxial, radially expandable wall portion of the
end to be secured protrudes beyond the plate; an generating pressure in a
closed hollow space surrounded by the wall portion with a pressure fluid
until the wall portion radially expands and anchors the centering pin.
According to another method, the end is introduced into the bore until at
least part of the end to be secured, which has a periphery and an interior
with radial slits formed therein, protrudes beyond the plate; and a
mandrel-like tool is partially brought into the slits in the interior of
the end of the centering pin and radially expands the end of the centering
pin with the tool for anchoring the centering pin.
Davis et al., U.S. Pat. No. 4,954,017 describes an expansion bolt, adapted
to be anchored in a hole, having a hollow shank portion adapted to hold a
pressurizing fluid and to expand girthwise on pressurization of the fluid,
and further having a threaded portion adapted on insertion of the shank
portion in the hole extend out of the hole and to have a nut threaded
thereon, whereby, following insertion of the shank portion of the bolt, in
an unexpanded condition, in the hole, the shank portion may be expanded by
presssurization of fluid therein for anchoring it in the hole and the nut
threaded up on the threaded portion of the bolt.
Arkinstall, U.S. Pat. No. 5,287,852 describes a releasably anchorable
bushing conduit apparatus for providing access through a wall having a
generally accessible side and a generally inaccessible side and an opening
extending through the wall from the generally accessible side to the
generally inaccessible side comprises a bushing conduit having first and
second opposite end portions with first and second coterminous openings
therein. The bushing conduit is insertable into the opening such that the
first end portion protrudes from the wall on the inaccessible side and the
second end portion protrudes from the wall on the accessible side. A
retaining device external to the first and second coterminous openings
retains the bushing conduit in place, yet presents no obstruction to the
first and second coterminous openings. The retaining device includes an
expandable and collapsible member secured to the first end portion and
capable of expanding to interfere with the inaccessible side to prevent
the first end portion from being withdrawn from the opening from the
accessible side. The expandable and collapsible member is also capable of
being collapsed to prevent interence of the member with the inaccessible
side to permit the first end portion to be withdrawn from the opening. A
device is provided on the bushing conduit for squeezing the wall between
the expandable member and the second end portion to hold the bushing
conduit securely in the wall opening.
Gudmundsen, U.S. Pat. No. 2,342,732 relates to rivets and riveting to
provide a novel rivet and method of setting the same which obviates the
need for holding an anvil against the head of the rivet during the
riveting operation and instead permits the setting operation to be
completed entirely from in front of the work.
Higley, U.S. Pat. No. 2,415,560 relates to rivets of the fluid expansion
type and more particularly to a rivet in which pressures may be generated
internally of the rivet through the application of an initial fluid
pressure and a mechanical pressure. The invention further contemplate the
new and improved method of binding a rivet of this type. An important
object of the invention is to exert in a rivet of the fluid expansion type
an initial internally generated fluid pressure outwardly of the rivet
effective to expand the rivet and also to exert a cooperating pressure
along the rivet. Another object of the invention is to bind a rivet of the
above mentioned type by the application of a pressure consisting of an
initial fluid pressure and a cooperating mechanical pressure ends
effectively greater. It is also an object of the invention to provide a
simple and inexpensive rivet construction by which the foregoing objects
may be carried out.
Jakosky, U.S. Pat. No. 2,342,866 relates to hollow rivets which are set or
expanded by hydraulic pressure within the rivet. Such rivets have a hollow
shank closed at its set-end and constituting a hydraulic pressure chamber
which is open through the head of the rivet. Hydraulic pressure is
supplied through the head to expand the shank into tight contact with the
rivet hole and to form a head on the projecting or set-end of the shank.
This is achieved by stretching the wall of the shank. Such rivets are
highly satisfactory for many uses but these uses are limited on the one
hand by the relatively low strength in shear of the hollow shanks and on
the other hand by the pressures which can readily be applied by hand tools
or to delicate parts being riveted to expand the shanks the requisite
amount. It is among the objects of the present invention to increase the
shear strength of hollow rivets and to reduce the pressure which is needed
to set rivets of a give strength.
Dexter et al., U.S. Pat. No. 2,359,629 relates to hollow rivets which are
set or expanded by the pressure of liquid forced into the rivet by a
pressure-applying tool. This invention provides an improved hydraulically
expanded rivet in which expansion of the shank to fill the hole is assured
and to provide a rivet which expands more nearly uniformly outside of the
rivet hole to form a strong symmetrical head free of rupture. The
invention also provides a rivet which exerts a greater axial compressive
force on the plates or objects to be riveted than previously known
hydraulic rivets and thus provides a tighter joint. This is important in
the construction of fluid-tight containers.
Dailey, U.S. Pat. No. 3,040,393 provides an elongated member, in particular
a ring of the character described which is economical to construct
efficient in operation and which is characterized by the facility with
which it may be mounted in operating position. More specifically it
provides an endless annular, elongated sealing or like member formed of
yieldable resilient material and adapted to be mounted on support
structure including means defining a narrow elongated opening also annular
in character, the member having provision to control the direction of
collapse of the tube when evacuated for insertion in the opening. The
present invention also provides useful articles such for example as self
locking filler strips, sealing strips, refrigerator door seals, joining
strips, glass mounting channels, water deflector seals, trunk seals or the
like, all characterized by the inclusion of elongated collapsible tubular
portions having means for controlling the direction of collapse of the
tube when evacuated to facilitate insertion of the tubular portion in the
opening of the support structure.
The prior art teaches the use of expandable elements for enabling the tight
fitting of rivets and other fasteners. An important reference, V. D.
Dailey, teaches the use of vacuum for enabling the fitting of a
contracting element. However, the prior art does not teach that an
elongated and linear element may be fitted for engaging two structural
elements and may be expanded or contracted by a fluid as necessary for the
assurance of the desired relationship between these elements. The present
invention fulfills these needs and provides further related advantages as
described in the following summary.
SUMMARY OF THE INVENTION
The invention is a connection assembly and sealing profile/joint which
becomes effective through expansion. Its connective and sealing effects
are achieved by the force of pressure within an elastic hollow member
which is able to conform to the groove, slot or other feature into which
it is placed. Hydraulic or pneumatic pressure means may be employed and
may be temporary or permanent. The distinguishing feature of the invention
is a closing effect produced by the application of fluid pressure in an
elastic tube or hose whereby the tube or hose conforms to the surfaces
surrounding it thereby achieving a strong connection therewith.
Applications include sealing and locking doors and other portals, creation
of a flexible hinge mechanism as for doors, aircraft wing flaps and other
similar applications, and as an interconnection medium for flexible belts,
chains and other drive links.
The present invention teaches certain benefits in construction and use
which give rise to the objectives described below.
The present invention provides a linear joining device comprising a first
receiver member providing a first closure surface thereon and a first
linear cavity therein, the first closure surface communicating with the
first linear cavity along a first linear aperture defined in the first
receiver member; a second receiver member providing a linear sealing means
mounting means; the first closure surface being positionable for aligning
the first linear aperture in mutual linearly corresponding adjacency with
the linear sealing means mounting means; an elongate linear elastomeric
sealing means engaged within the first linear cavity and the linear
sealing means, and extensive therebetween; the sealing means providing a
first linear channel therein, the linear channel responsive to fluid
pressure for expanding the sealing means within the linear cavity so as to
enable the first and second receiver members to be mechanically joined
when desired.
The invention is a connection assembly and sealing profile/joint which
becomes effective through expansion. Its connective and sealing effect is
achieved by impact of pressure within an elastic hollow member which is
able to conform to the groove, slot or other feature into which it is
placed. Hydraulic or pneumatic pressure means may be employed and may be
temporary or permanent. The distinguishing feature of the invention is
that of a closing effect produced by the application of fluid pressure in
an elastic tube or hose whereby the tube or hose conforms to the surfaces
surrounding it thereby achieving a strong connection therewith.
Applications include sealing doors and other portals, creation of a
flexible hinge mechanism as for doors, aircraft wing flaps and other
similar applications, and as a interconnection medium for flexible belts,
chains and other drive links. Applications include manufacture of
automobiles, aircraft and ships, satellite systems, steel and concrete
construction, erection of homes and buildings, bridge and road
construction. The important advantage of the invention is in weight
savings, flexibility, easy maintenance and low cost. For example, typical
doors are interconnected with their surrounding structure by hinges and
door locks, a relatively few points of contact. Application of the present
invention can result in a continuous interconnection between door and
frame. This is an important consideration in that the interconnectedness
may be constructed so as to receive shock loads without deformation, may
be formed fluid tight so as to prevent gases and liquids from passing and
may be easily replaced when necessary without undue expense.
A primary objective of the present invention is to provide a closure and
interconnection means having advantages not taught by the prior art.
An alternate objective is to provide such a closure-interconnection means
enabled for providing closure between primary structural rigid members
over an extensive linear runway including sealing of entire perimeters.
Another objective is to provide such a closure-interconnection means
enabled for providing control of the tightness of fit between the primary
structural elements involved.
A further objective is to provide such a closure-interconnection means
enabled for providing repetitive closures and openings.
Other features and advantages of the present invention will become apparent
from the following more detailed description, taken in conjunction with
the accompanying drawings, which illustrate, by way of example, the
principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION
The above described drawing figures illustrate the invention, a linear
joining and sealing device which will be referred to simply as a joining
device herein. The linear joining device, in a first embodiment shown in
FIG. 1, comprises a first receiver member 10 preferably of a rigid
structural material such as wood, metal or plastic, providing a first
closure surface thereon 20 and a first linear cavity therein 30, the first
closure surface 20 communicating with the first linear cavity 30 along a
first linear aperture 40 defined in the first receiver member 10 and may
be as long as desired and may close upon itself; a second receiver member
50 providing a second similar closure surface 60 thereon and a second
linear cavity 70 therein, the second closure surface 60 communicating with
the second linear cavity 70 along a second linear aperture 80 defined in
the second receiver member 50 in the same manner as described above; the
first and second closure surfaces 20, 60 being positionable for aligning
the first and second linear apertures 40, 80 in mutual linearly
corresponding adjacency as shown in FIG. 2 such as in the case of a door
and door frame for instance; an elongate linear elastomeric sealing means
90, made of a material with at least some resiliency and shape memory such
as a rubber, a rubberized plastic or related materials which are well
documented in the art, engaged within the first and second linear cavities
30, 70 and extensive therebetween; the sealing means 90 providing a first
100 and a second 110 mutually parallel linear channels therein, the linear
channels 100, 110 responsive to fluid pressure for expanding (see FIG. 2)
the sealing means 90 within the linear cavities 30, 70, the first linear
channel 100 responsive for engaging the sealing means 90 within the first
linear cavity 30 and the second linear channel 110 responsive for engaging
the sealing means 90 within the second linear cavity 70 so as to enable
the first and second receiver members 10, 50 to be mechanically joined and
interconnected when desired.
In a Second embodiment, shown in FIG. 2, the device comprises a first
receiver member 10 providing a first closure surface 20 thereon and a
first linear cavity therein 30, the first closure surface 20 communicating
with the first linear cavity 30 along a first linear aperture 40 defined
in the first receiver member 10; a second receiver member 50 providing a
linear sealing means mounting means 55; the first closure surface 20 being
positionable for aligning the first linear aperture 40 in mutual linearly
corresponding adjacency with the linear sealing means mounting means 55;
an elongate linear elastomeric sealing means 90 engaged within the first
linear cavity 30 and the linear sealing means mounting means 55, and
extensive therebetween; the sealing means 90 providing a first linear
channel therein 100, the linear channel responsive to fluid pressure for
expanding the sealing means 90 within the linear cavity 30 so as to enable
the first and second receiver members 10, 50 to be mechanically joined
when desired. The sealing means mounting means 55 may be any mechanical
clamping device capable of supporting and anchoring the sealing means 90
on a second closure surface 60 of the second receiver member 50. As shown
in FIG. 2, the sealing means 90 may be formed with a flange 130 for
mechanical mounting under the clamping device 55. In the embodiment shown
in FIGS. 1 and 2, the sealing device 90 might be used to seal a door as
referenced by numeral 10, to a bulkhead, as referenced by numeral 50. Such
a seal may extend fully about the door's perimeter for an airtight seal.
When the medial portion 92 of sealing means 90 is of sufficient length, the
sealing means 90 is able to function efficiently as a hinge whereby fluid
pressure is used to expand sealing means 90 within one or two of the
linear cavity so as to form an integral assembly as shown in FIG. 2. It is
clear that a fluid may be used for the expansion of the sealing means 90
such that upon curing the assembly is permanent and not dismountable
without destruction of the components.
Preferably, the sealing means 90 further comprises an exterior surface
layer 120 of a structural material, the exterior surface layer 120 being
integral with an exterior surface 92 of the sealing means 90, the exterior
surface layer 120 being adapted so as to be flexible with the sealing
means 90. This is achieved when the exterior surface layer 120 provides a
linear means for flexing 122 so as to enable the sealing means 90 to
change shape. Such a linear means for flexing 122 preferably comprises a
plurality of linear grooves or may simply be a structural yet flexible
material such as a spring steel sheet.
As shown schematically in FIG. 4, the device preferably further includes a
means for injecting 130 a fluid into the first, and or second linear
cavity 100, 110, such as a pump or pressure cylinder used in conjunction
with an inlet valve (shown as V1 and V3 in FIG. 4), and a means for
exhausting the fluid from the linear channels 100, 110 such as an outlet
valve (shown as V2 and V4 in FIG. 4). Valves V1 and V3 are preferably
solenoid actuated valves with a back-flow inhibiting feature as is well
known in the art. Valves V2 and V4 are common solenoid actuated exhaust
valves as are also well known in the art.
While the invention has been described with reference to at least one
preferred embodiment, it is to be clearly understood by those skilled in
the art that the invention is not limited thereto. Rather, the scope of
the invention is to be interpreted only in conjunction with the appended
claims.
